Citi .NET Lead interview questions

I applied through their company website. The HR called after a week to schedule F2F interview. However, due to my personal date constraints had a Phone interview instead. The HR was accommodative enough. The interview was a totally technical and the candidate was expected to possess very good knowledge of .NET framework in general and various feature, changes that have been made to .NET over the years such as EF, WCF, WPF, Web API, Mobile web app development and so on. There were no programming questions but verifying of basic concepts in general.
